AE1200 loses connection after 15 minutes

    The issue: the AE1200 wifi adapter consistently loses connection after 10-15 minutes, and I have to use the "Repair" option or disconnect & reconnect or remove the adapter and plug it back in to restore the connection.
    It would appear that I do have the latest driver, but a system search revealed that the associated files are in rather odd places or not found. I am attaching a list of the driver and associated files' locations.
    I'd appreciate it if you'd look at the list and let me know whether or not the files are where they [​IMG][​IMG]should be.
    If they are not, should I uninstall the drivers and start from scratch?
    Also, on the off chance that the advanced settings may be incorrect, I'm also attaching for your review a file showing current settings.
    Thank you very much for your attention.

    I see that the images in my post didn't get properly "inserted". Although most have probably figured out (it took me a while) that the URL is available by right-clicking and choosing "Copy image location" or "Copy image URL", here are the links with no "image" intermediary:

    I'd like to thank everyone for the attention given so far (I see that my post has been read over 50 times), and I'm still hopeful there's a way to fix things. If it turns out there are no "fixes" (drivers, settings, etc), perhaps I should be asking for recommendations of brands of USB wifi adapters that actually work ;-)

    Kind of disheartening that nearly 100 folks have read my post, but so far no one has offered any suggestions. I've uninstalled and reinstalled the drivers, even went to the extent of putting in a USB 2.0 card in my computer (didn't that would make a difference) and nothing is different. I'm convinced the AE1200 is a P.O.S.
    Being that this is a Linksys-oriented forum, it may be inappropriate to do so, but does anyone have suggestions for a USB wi-fi adapter that actually works?

    How strong is the signal strength? Any outside interference from cordless phones or other wireless calls broadcasting on the same WiFi Channel?

    You have also only mentioned one HF of the equation. What WiFi router/access point are you using?

    Thank you for your interest.
    Signal strength 99% of the time is 54 Mbps, once in a while dipping to 48 Mbps. Both AE1200 status info and the Task Manager Networking tab agree on these figures, although both report these speeds even after the AE1200 ceases to work and needs to be "repaired" to restore connection. Only very rarely does the AE1200 display a "no connection" popup when it picks up on the fact that it isn't working anymore.

    The router is a Trendnet TEW-652BRP, located on the first floor; the computer with the AE1200 is on the 2nd floor, almost directly above it.. It is set to Channel 6.

    There are no cordless phones in the house. Wireless connection problems do not occur with my laptop, nor do they occur with the laptops of 2 other people in the house. Cell-phone interference is also ruled out, as the AE1200 behaves just as poorly whether or not there are cell phones in the house.
    Thanking you again for your interest...

    Thank you, Toxic, for the information. Actually, I did have a look at the possibility of interference, but Inssider turned up nothing significant. I really did not to find anything anyway, as the issue is not strength of quality of signal/connection. The issue is presence or absence of connection. As mentioned before, I am the only one in the household with wifi connection problems --- and I happen to be the only one in the house with a Linksys AE1200 USB adapter. My own laptop has no problem and I've used it in the exact same spot I'm now using the AE1200. Signal strength or possibilities of interference are not issues.

    An interesting side-note: I noticed on my Task Manager a "ghost" CPU usage of around 15% (i.e. CPU usage not accounted for by Task Manager ---- like System Idle 98%, but total CPU usage showing 20%, when it should show 2%)
    The "ghost" user, it turned out (of course) was the AE1200.
    (screen shot here ---

    I later learned thru Process Explorer, that AE1200 was causing the CPU usage thru what are known as "Hardware Interrupts" (AE1200's way of communicating with the system).
    screen shot here --

    The AE1200, on average, accounted for about 18% CPU usage. I don't think any hardware should be interrupting that much, do you?

    So --- what do you think of D-Link? Think I might have better luck? Any recommendation would be greatly appreciated.

    Thank you.

    Thank you, Toxic. I've just tried to update the drivers with those from the wikidevi link you provided above. I pointed the Wizard to the folder I created with the new drivers and the Hardware Update Wizard said: "Cannot continue the Hardware Update Wizard. The wizard could not find a better match for your hardware than the software you currently have installed."
    (I've noticed that the drivers I have (recently downloaded from the Cisco site) and those from the wikidevi site are both version; but oddly enough, the file creation dates are different --- those that I have from Cisco were created 6/10/2011, and those from the wikidevi on 3/29/2011. If I remember correctly, 3/29/2011 was the creation date of the drivers I started out with before I updated them with the download from Cisco. Weird. Probably doesn't make any difference, but it's a bit puzzling).

    Thank you very much for the interest you've shown and the attention you've given to my problem. I really appreciate the help. Also very open for any other suggestions . . . (by the way, is there any particular model number of d-link or netgear adapters you'd recommend?)

    Thanks again.

    Having come to the conclusion that the Linksys AE1200 is an unredeemable piece piece of garbage, I bought another USB adapter: d-link dwa-125.
    It works.
    It actually stays connected.
    Also, Process Explorer shows that its "Hardware Interrupts" consume only between >0.01% and 3.10% CPU usage, which seems more reasonable to me.
    I'm happy. Just pissed that I spent $30 for a piece of junk and to find out that its $20 counterpart was the one I should have bought in the first place.
    Caveat emptor (particularly if you're empting Linksys products).
